Did a hacker or group of hackers, possibly in Russia, manage to physically destroy a water pump in Springfield, Illinois? That was the word last week, when reports spread that hackers had managed to take control of the water plant's Supervisory Control and Data Acquisition System (or SCADA), which gave them the ability to repeatedly turn the pump on and off and eventually burn it out. Now, however, both the FBI and the Department of Homeland Security say that their investigations have found no evidence of hacking or malicious activity, and that earlier reports were based on "raw, unconfirmed data." As you might expect, that explanation isn't quite being accepted by everyone, including Joe Weiss, the security researcher who first reported the incident.
